Some grammar fixes to 'Format String Checking', and reorder the text slightly to try to make the final code block actually get rendered.

I'm using the name "Extended Identifiers" for the feature because that's
what GCC calls them. According to the standard, the new feature is
"universal character names are now allowed in identifiers", but the more
interesting "feature" is that identifiers can now contain Unicode characters,
however they are written.

This is a powerful tool when doing iterative refined matches,
where another match is started inside the match callback of the first
one; this allows for example to find out whether the node was in
the condition or body of its parent if-statement.

This is in preparation for adding other overloaded matchers. This change
alone is a net win in LOC.
I went through all matchers and looked whether we could now encode them
as macro, or simplify them with the matcher atoms that were not
available before.

This is a text file with Markdown-ish formatting because we haven't decided
where analyzer internal documents should go, but it's probably better to
have this in source control than sitting on my local drive forever.

Revert "Remove sparse text on diagnostic options.  These are not really documented anywhere, and they really aren't for normal users."

I changed my mind.  We should just document these in the man page.

We found that findAll has been implemented incorrectly multiple times
by various people using the matchers. To prevent further wasted
development effort, it makes sense to add it as convenience matcher
implemented as eachOf(m, forEachDescendant(m)).

This patch also updates the docs with the new matchers.

implementation; this is much more inline with the original implementation
(i.e., pre-ubsan) and does not require run-time library support.

The trapping implementation can be invoked using either '-fcatch-undefined-behavior'
or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter
being preferred.  Eventually, the -fcatch-undefined-behavior' flag will be removed.

Clang doesn't understand it.

If someone wants to teach clang about that flag instead, please also add
support for -fno-diagnostics-parseable-fixits for consistency.

Until then, let the documentation match the current behavior.
